In addition to the intrinsic properties of the active substances in lithium ion batteries, the microstructure of the electrodes has a great influence on the energy density and electrochemical properties of batteries Of the uncrushed electrodes, only 50 % of the space is occupied by active substances, which improves the compaction density and can effectively increase the volumetric energy density and the weight energy density of the electrode.

Many people in the industry claim that 2018 is a key year for the lithium industry, and these six months, whether good or bad, have been cited as unclear, and it is indeed an eventful period In April, many lithium power companies made different survival decisions.

A brief introduction of accomplishmentsCharging issue is the bottleneck of the current electric car development Energy Internet innovation Tsinghua university institute of energy use Internet making use of "time-sharing" concept, independently research and develop the electric car sharing time-sharing charging power supply system, which can greatly improve the ability of power distribution network management charging pile.

With the continuous reduction of petrochemical fuel and increasingly serious environmental pollution, the development of new energy vehicles has risen to the level of national strategic goals In 2017, China sold more than 700,000 new energy vehicles.

On February 21st, Beijing Carbon Century Technology Co, Ltd.

The mainstream of electric vehicles on the market is divided into lead-acid batteries and lithium batteries From the perspective of the market share, lead-acid batteries are far higher than lithium batteries.

In lithium batteries, all-solid lithium batteries are recognized as an important development direction for future secondary batteries from the perspective of improving safety However, one of the biggest problems with the use of solid electrolyte materials is that the conductivity of lithium ions in solid electrolytes is at least an order of magnitude lower than that of conventional liquid electrolytes.

As can be seen from the battery recycling experience of developed countries in Europe and the United States, the primary responsibility for battery recycling lies with the power battery manufacturers in establishing the recycling system for used and end-of-life batteries When electric vehicles equipped with power batteries are sold together to consumers such as operators, group customers, or individual customers, consumers have the ownership of power batteries and are also obliged to pay for power batteries that are scrapped.

Lithium-powered battery is a new type of high-energy battery developed successfully in the 20th century The negative electrode of this battery is metallic lithium, and the positive electrode is MnO2, SOCL2, (CFx) N, etc.

After receiving a 13 billion yuan acquisition invitation from Gree Electric, Yinlong New Energy became the focus of market pursuit and discussion The reporter also went to the Yinlong New Energy Automobile Factory in Handan, Hebei Province to find out.
